Introduction to the working principle of common muffler
What is a muffler? In fact, this is a tool that prevents sound and noise from spreading and allows airflow to pass. It is often installed in blowers, generators, water pumps, and air compressors that are noisy when aerodynamic equipment is started, which can reduce the noise they generate. . There are many types of mufflers, which can be roughly divided into six types based on their principles. Resistance, impedance composite, micro-perforated plate, small hole, active and resistive muffler, what are their principles?
The resistant muffler is formed by a combination of a chamber and a pipe. It is reflected by the sudden change of the pipe in the body or by the adjacent resonant cavity, and interferes to reduce the noise to achieve the ultimate goal of silencing. Impedance composite muffler is a new type of muffler, which is a muffler that combines a resistive structure with a resistive structure to achieve the purpose of silencing. The micro-perforated plate muffler is a new type of muffler with high acoustic resistance and low sound quality. It does not require porous sound-absorbing materials and only uses small holes drilled in the metal plate to form a micro-perforated plate sound-absorbing structure. The small hole muffler is a muffler that can organize noise without obstructing air flow. It is formed by internal acoustic treatment. Active muffler is a muffler that uses electronic facilities to generate a sound wave equal to the original sound pressure, so that it cancels each other out. A resistive muffler is a type of muffler that uses sound waves to propagate in a porous structure and converts frictional sound into heat energy to eliminate noise.
Knowing the principle of the muffler can give you a better choice. In use, you must choose a more reasonable muffler that is more suitable for you, so as to maximize the reduction of noise. We provide silencers. If you are interested in silencers, please contact us for more information.
